[Lxc-users] Running LXC on a pxelinux machine

Unfortunately I haven't managed to get any further :(

I can still ping the LXC containers from other hosts on the network, and
they can ping each other, but I cannot ping them from the pxelinux host
machine.

Comparing the network config between the pxelinux host and a
non-pxelinux host I can see that the pxelinux host has an IP associated
with eth0 while the non-pxelinux associates the IP with br0. I've tried
various attempts to reassign the ip address on the pxelinux host to br0
but to no avail (attempts result in hanging the machine).

Any more pointers would be a great help!

Gus.
